Question about Dell E173FP 17" LCD Monitor

1 Answer

Monitor lives its own life ;) Turnes off and on in random moments

My monitor seems to be ok, and as long as it displays stays ok. But when I reboot PC, and there's obviously no signal, when monitor goes black (green light turns to orange - like in Standby), it stays this way. Sometimes for 3 hours, somtimes for 3 days. The Power button does not work at all (orange all the time) Unplugging VGA wires or power does not help. Basically everytime I turn PC on it's 50% chance that it will work, and when you let it get to standby there's 90% chance it will remain black. This is not pain as I use it as a secondary screen, but it's huge inconvenience. I've read somewhere, that it's only a faulty capacitor, but cannot find that post. Please help

    Thanks, but this did not help. Actually that's one of the ways of saying nothing

  • Marek Perczynski Feb 01, 2007

    HI.
    I'm sorry you feel insulted but please understand my point.

    1. It sounds like there's a problem in the power supply or inverter section - these are only two there are (apart from the screen)

    2. and it's just teetering on the edge of failure. - no news in it either.

    3. The disruption of the signal is apparently just enough to kick it over the cliff until it's reset. - that's what i described right ?

    4. Sooner or later, it'll need some help, like - connections,
    - capacitors,
    - output transistors,
    - capacitors,
    - transformers.

    Those are the most common failures in these.
    - you did not mention resistors.

    Once again sorry you feel insulted, but we post on this forum to find people with the same (or similar)problem to find out what to do, - not just to read a list of obvious parts used by manufacturer and find out that any of them might be wrong.
    With all due to respect that is exactly what we know before posting. Regards

Sooner or later, it'll need some help, like connections, capacitors, output transistors, capacitors, transformers. Those are the most common failures in these. I think you'll see it get worse

    Sorry no magic wand exists, but you don't have to insult me by declaring that I was "saying nothing".

    I work on these all the time. It simply needs to be repaired.

    No mere words will actually help. The only thing that will help is when someone repairs it.

    If you can't do it, I urge you to take it to a shop.

    Okay. As I say, I work on these all the time. I actually refurbish them.

    For good measure, I replace all four of the output transistors with TIP41Cs because they handle the power much better and don't get so hot.

    It requries a little cutting on one the metal shield so the tabs of two of the transistors won't short. That will be obvious.

    The output transistors are the little tabbed ones between the output transformers.

    I also replace all the polarized electrolytic capacitors on the main board, even though only one or two may be bad, because the batches they use seem to all go bad sooner or later.

    I use good quality caps rated at 105C.

    I then resolder quite a few connections in the power and inverter sections to prevent future trouble.

    Now if you just want to get your current problem fixed so it will work until one of the other above components or connections fails, I would suggest that you look for bulging or leaking caps in the power supply section.

    The first suspects would be the caps located by the group of three heat sinks - that's roughly the area between where the video board plugs in and the main large power supply capacitor is.

    That's as specific as I can get. Good luck.

You have computer problem, you can easily verify by using this monitor with another PC or another monitor with this PC.
It may be video card driver problem, since the PC was not properly shutdown, it will give you that message "boot in safe mode or normally".

Without looking at the monitor to confirm this, I suspect you have failing capacitors which power the HT circuit, simply, the power needed to light the display, is leaking to earth, capacitors have lost the ability to store the charge necessary to illuminate the screen, which is why it is working erratically.
You need to get this checked out by a TV technician.

My monitor randomly turns off.


Most likely you have a bad INVERTER BOARD.

2nd in line is a burned out backlight fluorescent bulb.

My monitor won't stay on every time I reboot the computer


might be the connection from your computer to your monitor. the cord may be malfunctioning. that's where the "analog" is coming from.

the video card could be bad.

or, the monitor itself could have a short.
when you mess with the buttons, it's "moving" something inside the monitor that is keeping that short from being a problem.

Laptop monitor goes black


If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time

I hope this helps.
